TIE auimsl. If pronouUc.u In Is con-
ditioD, Is trotted upstairs and given one
VI the little stalls in the top story. There
ne is ailo1et to remain uutil he has fed
we'll and is feeling "a though he had at
last found comfortable quarters. Then
he is hauled out by his nose ead tail g
The opsrating-rooGl. There he ia hello
quietly until one OF the attendants
buckles Strap around his left hind leg.
This strap, attached to g. pulley rope, IS
given strong pull by al ATTENDANT and
up goes the ca!f On the yaccinasing tebIe
VIII tlud AID snort OF decided dis
pleasure. But his struggles are utterly
useless, Tor ny this Ifnc : heavy band is
buck;ed over his hose ahd TT Ok and fore
legs. Theu Dc IS ~ rhe mercy of the sur
geUn. Bus this latter does not vaccinste
a. ooce. H2 l.iheIs the Inside of the
Calls hind legs and then carefully shsves
away al the hair. Tnen the animal is a.
lowed 10 go back to his sail and rest
while until the VacciDatOr has arranged
his virus and his vaccine 'spades.n
These are long points Of bone, and are
used on the calves because they will hold
more Of the virus than the ordinary quill.
B cause they ere big and mold more thas
sufficient virus TO Vaccinate IN infant they
are keps exclusively tor the animals.
After rest OF an hour or So the csif is
trOtted out Of mis- stall again aud again
tossed on It's side upon the vaCcizskiug
board. Then the real work begins. The
doctor takes big SIX bladed lancet, and,
h ,ldiDg the knives together, cuts the
shaven skin of The nimsl SO as TO last
pierce the outer layer. Than the operator
q 'es his lancet at right angles with the
original cuts, and SO a0rsde the skin thst
it will readily receive the virus from the
"spade." But the "spaGan is rot used at
frst. The work begins thus: AL the blood
is carefully cleaned away from the
ABRASION, and then q Qnll holding .
small amonnt Of virus is rubbed upon the
spot. Tnen Comes Lne spade" which
holds about four times as much virus IS
the ordinary quill. Tee virus from this
is rubbed in carefully, a1d then the calf is
led back TO his stall. AS rule fur alb
rasiops are made upon the shaved skin Of
the animal.
According to the statements of the
physician in charge Of the vaccine stable,
the calves show no evil ef. cts from the
vaccination. Their appetite Is unim-
paired; in fact, they eat more than they
did before the operation, and show none
the ,assitude infants and adults do
after vaccination. Their allowance Of
food is increased. In this way the calves
are treated for about seven days, when
the virus has done its work, and
again the animal is placed upon the op-
Grating board, sad then the important
BUSINESS of collecting the virus begins.
For doiog this quilts and "spaies" are
prepared for the reception Of the virus.
The quilts, which are taken from Russian
geese, are purchased from an importer
named De Young, who charges the
Health Departmei elo per 1000 for them.
They are tied up ia baadlss of 1oe
and sent to the vaccine stables, where
men cat them into convenient ler .ths
and scrape the ends sc that they will mold
virus. The animal is placed upon the oP-
Grating board as before aad The rough
sned end of the quill used to take vac
cine. Then cones the drying process
and subsequently, the treated quilts are
put into Theoretically sealed jars and
stored In an ice closet.
